Stress relaxation of model poly(dimethylsiloxane) networks with pendant chains and nearly constant cross-linking density was studied. The networks were obtained by end-linking a mixture of long chains bearing terminal ...

We have estimated the mass fraction of elastic and pendant chains of model poly- (dimethylsiloxane) (PDMS) networks using transverse proton relaxation in nuclear magnetic resonance (1H NMR). These experiments were compared ...

Model silicone networks obtained by curing linear poly(dimethylsiloxane) (PDMS) chains with end-vinyl groups, (B2), with a polyfunctional silane-terminated crosslinker of functionality f, (Af), through a hydrosilylation ...

The relaxational dynamics of trapped entanglements in model silicone polymer networks is studied through the residual dipolar couplings (RDC) obtained by double quantum nuclear magnetic resonance (DQ NMR). These experiments ...

This work analyzes the relationship between the shear relaxation modulus of entangled, linear and flexible homopolymer blends and its molecular weight distribution (MWD) when a fraction of the sample contains chains with ...

We analyze the dynamic response of end-linked poly(dimethylsiloxane) networks containing entangled unattached guest linear polymers. Upon increasing the content of unattached guest polymers there is an increasing dissipation ...
